nmn'aenncv VALVE AND CONTROLLING Means THEREFOR.

Application filed February 9,; 1823. Serial No. 618,167.-

This invention relates to improvements in gency valve and controlling means therefor emergency valves and actuating means therefor more particulariyva'dapted for use with truck tanks for dispensing gasoline, oils, etc.

Trucktanks for dispensing gasoline, oils, etc. are usually divided into compartments for holding fluids of different kinds or qualities and the compartments are provided with discharge pipes which extend to the rear. portion of the truckv and have faucets for V controlling the flow therethrough; As thus constructed the faucets are apt to become damaged and the entire contents of the tankwill be discharged from the tank and lost. Furthermore by the necessary positloningof the faucets at the rear end of the truck at the point of delivery of the fluid, the faucets are more apt to be injured by the operators in dispensing the liquid, and if injured in anymanner the contents of the tank are liable to be lost.

It is one of the objects of thepresent invention to overcome the before mentioned objectionable features and provide an emergency valve and controlling means therefor which will control the flow to the faucets and which normally is in closed position and halekto be opened to draw the fluid from the ta Y A. further object of the invention is to provide an emergency valve which is located within the tank and opens against the pressure of the flow.

A further object of the invention is to provide an emergency valve which will prevent the loss of gasoline through collision or fire resulting therefrom as gasoline cannot leak from the tank into the street. Furthermore, the construction revents tampering with-the tank or the acc dental or otherwise openin of the faucets and the loss of fluid 7 when the emergency valves are opened.

from t e tank. f

provide an emergency1 means therefor whic while normally in a closed position'isadapted tobe easily opened 1 and closed from the rear portion of the truck.

A further object of the 1nvent1on is'to provide an emergenc .valve and controlling means therefor whic is of simple construction, is strong and durable and is well adapted for the purpose described.

With the above and other ob]ects in view 'ing a portion of the-casing;

Fig. 5 1s a vertical sectional view of the the invention consists of the improved emerand its parts and combinations'as set forth 1n thecla ms and allequivalents'thereof.

" In-..the accompanying drawings in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is an inverted view, of atru'ck tank I provided w1th the improved emergency valves and controlling means therefor; 1g. 2 1s a side view in closed position of I an emergency valve and the controlling means therefor, a part being shown sec- Fig. 4 is a verticalsectionalview'of the valve on a larger scale, the viewalso showvalve taken on line 55 of Fig. 4;

Fig. 6 is a vertical sectional detail view of a modified form of valve;

- Fig. 7 is a side view partly in section of Fig. 8 is a similar view in open position. 1 1

Referring to the drawings the numeral 10 indicates the bottom portion of a truck tank showing the parts which is u'sually divided into compartments 11 by partitions 12. One of the improved emergency valves 13 is mounted in the lower portion of'each compartment and is usually provided with branch pipes 14 which extend to the rear end portion of the trunk. Faucets 15 mounted on said rear endportions of said branch pipes control the flow of the gasoline, oils, etc. through said branch pipes Each valve comprisesa casing16 having a threaded portion 16' which threads into the bottom portion of the tank and a valve seat portion 17 which is closed by a stem .a modified form of actuating means for the valve shown 1n closed position; and

valve 18; The casing is formed with an up- 7 ward extension 19 having side openings 20, and a guide member 21 threaded into the upper open end of the extension has the stem 18' of the valve 18 extended and guided therethrough as shown in Fig. 4. The valve stem is formed with an annular shoulder 22 and a coiled spring 23 surrounding said valve stem and interposed between the stem shoulder and the upper end .portion of the guide member yieldingly holds the valve in.

. closed position; As thus. positioned the valve opens against the pressure otthe flow of the fluid from the tank and when the valve is in open position the fluid will flow through the side openings 20 and the valve casing and the'branchtubes 14 and be discharged through the faucets 15.

The valve casing l6i' formedwith a tubular side bearing portion 24 in'whichv is journaled a short valve shaft 25 having an inner medialsquared portion upon which is mounted theouter end portion of a valve arm 26. The inner end portion of said valve arm 26 is pivotally connected to the lower end-portion of a connecting rod'27, the upper end portion of which is pivotally connected to the lower portion of the valve 18.

The outer end-portion of the shaft 25 extends through a stufling nut 28 wand is j squared to receive an arm 29 mounted thereon. Said. arm 29v depends downwardly therefrom and at its lower end'is pivotally connected to the inner end of an actuating rod 30 which extends horizontally towards the rear end of the truck. The rear or outer end of the nod is provided with a T-shaped' handle 31 revolubly mounted thereon. Said handle extends s'lidably through an T elongated opening or slot 32, formed in a bracket member 33 depending downwardly from the truck, and is provided with short upper and lower ribs 34 which permit movement of said handle through the elongated o ening when the T-shaped portion 31 of the andle f is in horizontal position. When the handle form shown in Fig. 6 the opening 35 is in the bottom portion of said casing.

In the modified form shown" in Figs. 7 and 8 a single rod 30' is connected to all of the valve arms 29 and at its rearend is connected to the medial portion of an upwardly. extending lever 36. The upper end of said lever extends adjacent the inner side of a door 37 closing acan com artment38 at the. rear end of the tank, an said-door is pro vided with a bracket 39v which engages and pulls the lever outwardlyto open the valves when the door is swung to ,open"positi0 n.

The closing movement of the door will permit the springs of the valves to swingthe lever inwardly to closed'position.

From the foregoing description it will be seen that. the improved emergency valve and osithe controlling means therefor is of very simple construction and is well adapted for the purpose described.

What I claim as my invention is:
